A collection of routines for intelligently extracting data from PDFs: infer document structure from document content, extract data in tabular form, and detect interactive regions on a page.
Extract the underlying document structure in JSON form, yielding the position and content of paragraphs, tables and other structural elements. (DataExtractionModule.ExtractData(), using the e_DocStructure engine)
Use the tabular extraction engine to accurately extract data from your document in the form of tables, producing output in either JSON or XLSX form. (DataExtractionModule.ExtractData(), DataExtractionModule.ExtractToXLSX())
The form extraction engine can be used to recognize interactive elements on a page visually, so that the correct associated PDF annotations can be created. (DataExtractionModule.ExtractData() using the e_Form engine)
